【 摘 要 】

In this paper a new set of exact solutions of Einsteins field equations have been obtained for Bianchi type V space-time geometry. The first part of the paper deals with perfect fluid cosmological models in the presence of variable gravitational and cosmological constants. The second part of the paper is devoted to study the modified generalized Chaplygin gas model. The physical and dynamical behaviors of the models have been discussed with the help of graphical representation.
